The Hayes's ENERGY STAR score of 100 compares with an average of 85 across the 340 that report a score; it scores higher than 69% of them. Its site EUI of 14.0 kBtu/ft² is about 61% below the average of 36.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.8 kgCO₂e/ft² is about 62% below the group average of 2.0 kgCO₂e/ft².
At 227,503 sq ft, it is about 37% above the average floor area of 165,572 sq ft for those buildings. It was built in 2008, 42 years later than the group's average year built (1967).
How has The Hayes's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for The Hayes, covering report years 2018–2025. Its ENERGY STAR score was 100 in both 2024 and 2025. Site EUI moved from 13.9 kBtu/ft² (2024) to 14.0 kBtu/ft² (2025), an 1% increase. Reported emissions went from 174 tCO₂e to 174 tCO₂e over the same span (up 0%).
What does an ENERGY STAR score of 100 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In San Francisco, 73% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. The Hayes's 14.0 kBtu/ft² across 227,503 sq ft works out to about 3.2 billion Btu (933 MWh-equivalent) in 2025. Its source EUI of 24.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 376,769 kWh of electricity and 18,966 therms of natural gas for the year.
Which law requires The Hayes to report its energy use?
The Hayes reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:0854/011:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
